v0.8.0

GraphQL.js v0.8.0 is now compliant with the most recent version of the GraphQL specification! This release is also the first to include flow types in the NPM package, which should make it easier to use GraphQL in a well typed way. It also includes many new utilities and small improvements. Thanks to everyone who helped with this release!
